Carbon fiber bulkhead varies from six to 19 layers, and improves body rigidity by 33%.The spaceframe for the 2018 Audi A8 luxury sedan will use a mix of aluminum, steel, magnesium and — for the first time — carbon fiber. Compared to its predecessor, this multi-material mix increases torsional rigidity by 25%, though the weight of the body-in-white is up 112 lb. due to the need to meet ever stricter crash standards, and accommodate new powertrains. The new A8 is expected to have a 48-volt electrical system, as well as offer full hybrid and plug-in hybrid variants. This required adding structure to protect the lithium-ion batteries.
